Taking to Twitter, Biles began her letter with the following: “Most of you know me as a happy, giggly, and energetic girl. But lately…I’ve felt a bit broken. After hearing the brave stories of my friends and other survivors, I know that this horrific experience does not define me.”

“I, too, am one of the many survivors that was sexually abused by Larry Nassar,” she wrote. “Please believe me when i say it was a lot harder to first speak those words out loud than it is now to put them on paper. There are many reasons that i have been reluctant to share my story, but I know now that it is not my fault.”

“For too long I’ve asked myself, ‘Was I too naive? Was it my fault?’ I now know the answer to those questions. No. No, it was not my fault. No, I will not and should not carry the guilt that belongs to Larry Nassar, USAG, and others.”

The letter came a day before the beginning of a four-day sentencing hearing for Nassar, who is accused of sexually abusing more than 140 women and girls as the doctor for Team USA and Michigan State University, according to a report from NPR.

Nassar, 54, has pleaded guilty in Ingham County, Michigan, to seven first-degree sexual assault charges. However, before being sentenced, the judge overseeing the case has allowed all of his accusers to speak if they want to.
